MP6638

15V, 1.7A Peak, 3-Phase, Sensorless BLDC Motor Driver with Integrated MOSFETs

Description

The MP6638 is a three-phase, sensorless brushless DC (BLDC) motor driver with integrated power MOSFETs. It features sinusoidal sensorless control for better efficiency and low vibration with up to 1.7A of peak phase current.

The input voltage (V_IN) ranges from 2.5V to 15V. The MP6638 controls the motor speed through the PWM signal with the PWM input frequency (50Hz to 100kHz). The MP6638 also features rotational speed detection. The rotational speed detector (FG/RD pin) is an open-drain output.

Rich protection includes input over-voltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection.

The MP6638 is available in a UTQFN-8 (2mmx2.5mm) package.
